FRED STRAND AND AUSTIN STRAND, OF DENNISON, MINNESOTA.

LITTER-CARRIER.

Specification of Letters Patent.

Application filed February 21, 1910. Serial No. 545,153.

To all whom 'it may concern.' v

Be it known that we, FRED STRAND and AUSTIN STRAND, citizens of theUnited States, residing at Dennison, in the county of Goodhue, State ofMinnesota, have invented certain new and useful Improvements inLitter-Carriers; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to litter carriers and has special reference to adevice adapted to convey litter of all descriptions along wire and dumpthe lsame at a predetermined position.

One object of the invention is to provide an improved form of trip toactuate the lever which controls the release for the bucket common insuch devices.

Another object of the invention is to provide an improved constructionof angle iron yframe for devices of this description, the

ends of the frame being bent in a novel manner to provide metal forjournal bearings.

l/Vith the above and other objects in view, the invention consists ingeneral of a novel construction of frame supporting a dumping bucket, alatch for said bucket, and an improved form of trip adapted to beattached to a wire on which the bucket is carried.

The invention further consists in certain novel details of' constructionand combinations of parts hereinafter fully described, illustrated inthe accompanying drawings, and specifically set forth in the claim.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and z-Figure 1 is a side elevation of thebucket', the parts being in the position assumed when the bucket istraveling with a load, and the trip being in the position taken just atthe time the latch lever comes in contact therewith. Fig. 2 is an endelevation of a bucket constructed in accordance with this invention.Fig. 3 is a view from the side opposite to that shown in Fig. 1 and thebucket shown in its tripped position. Fig. 4 is a section on the line4-4 of Fig. 3.

This bucket is intended to run on a single wire which is here indicatedas at 10. The supporting frame for this bucket includes a casting 11having spaced legs provided with inwardly'turned ends 12 and an inwardlyand downwardly directed upper end 13.

Supported upon the upper end of this casting are longitudinal members14, the members being attached intermediate their ends to the frame. Oneof these members 14 lies between the body of the casting 11 and thedownwardly directed end 13 while the other member 14 is secured to thisend 13 on the side opposite the irst mentioned member. A single bolt 15passes through both members 14, the body of the casting 11 and its end13. The members 14 are thus spaced apart by the end 13 and at each endof these members are opposed openings for the reception of axle pins 1Gwhereon are mounted double flanged wheels 17 which run along the wire10. Spaced from the inwardly directed ends 12 the casting 11 is providedwith lips 18. The remainder of the supporting frame is made of a lengthof angle iron, the central portion of which is indicated at 19 and thiscentral portion lies between the ends 12 and lips 18 of the casting 11,being secured thereto by means of suitable bolts 20.

It is to be observed that one leg of the angle iron rests on the ends 12while the other leg rests against the casting 1l above said ends. Oneach side of this central portion 19 the angle iron is inclineddownwardly as at 21 and from the ends of these downwardly inclinedportions the angle iron is bent to extend downward as at 22, the twoportions 22 being parallel. The terminal portions of the angle iron arebent in such manner that the two legs come t0- gether as indicated at 23and these portions eXtend transversely of the wire 10 when the frame ishung upon the wire. By means of this bending orl the legs of the angleiron together a sufficient thickness of metal is rovlded so that it mayhave openings 24 tormed in each of the double portions for the receptionof trunnion pins 25 which are formed on trunnion castings 26. Thesetrunnion castings are secured to the ends of a trough-shaped dumpingbucket 27 and the bucket is so proportioned that when full the center ofgravity of the bucket will lie above the axis of the trunnions. On oneend of this bucket is secured an angle iron 28 of arcuate form and thecenter of the are to which this angle iron is bent is located above theaxis of the trunnions 25. Centrally of this angle iron 28 is an opening29.

On the inside of the angle iron frame at a point immediately above theangle iron 28 is a bracket 30 having spaced ears 31 formed thereon andthrough these ears extends a latch pin 32. AdJacent the lower one of theears 31 this latch pin is provided with a collar 33 xed thereon andbetween the collar 33 and the Lipper ear 31 is a spring 34 whichnormally tends to force the latch pin downward. On the same side of theangle iron :trame as the bracket 30 but located on the portion 21 onthat side is a pivot clip 35 to which is pivoted a lever 36, the leverbeing pivoted intermediate its ends and extending at one end from thepivot point to a point substantially above the bracket 30. This end ofthe lever is connected to the latch pin 32 by a link 37. The other endof the lever extends to a point beneath the center of the frame and isthere upwardly bent as at 38. On this upwardly bent end is carried aU-shaped striker 39.

The trip employed with this bucket consists of a U-shaped piece ofelastic metal of such size as to snugly embrace the wire l0 between thearms of the U, and this portion of the trip is indicated at 40. Throughthe arms of the U and adjacent the wire extends a clamping screw 4lwhich, when tightened, serves to draw the arms of the U together andclamps the trip firmly in position on said wire. Pivoted to this portionof the trip is a trip arm 42 of curved contour and this trip arm isconnected to'the clip 40 by means of a pivot bolt 43, the arm and boltbeing so positioned and proportioned that as the lower end of the arm 42is swung upward in one direction its motion will be limited by its baseportion 44 coming in contact with the wire l() as clearly indicated inFigs. l and 3. The motion of the trip-arm in the opposite direction ismuch freer and the arm may be raised so that it lies substantiallyparallel to the wire 10.

Reference being had to Fig. l it will be seen that as the bucket and itsframe move along' the wire the striker 39 will Contact with the trip arm42 and move the trip arm until its motion is arrested by its baseportion contacting with said wire. The trip arm wil-l then act upon thestriker 39 to move the same downward with the result that the lever 36will be rotated about its pivot and the latch pin 32 be drawn out of theopening4 29. This will release the bucket 27 which will automaticallydump and may then be moved back for refilling.

It is to be noted that the small shafts used for the axles of thesheaves are preferably of cold roll steel and that these sheaves `are tobe provided with roller bearings of any preferred form. It will furtherbe noted that the spring is such that the carrier travels about fourinches after the member' 39 engages the trigger 42 and is depressed bysaid trigger so that ample time is allowed for dumping the bucket.

There has thus been provided a simple and eflicient device of the kinddescribed and for the purpose specified.

Having thus described the invention, what is claimed as new, is:-

In a litter carrier, a tip bucket, a bail to which said bucket ispivoted, coacting latch means on said bail and bucket, a trip lever onsaid bail operatively connected to the latch means on the bail, and aguide end on said lever comprisinga plate bent to U-shape with the mouthof the U uppermost; in combination with a trip ringer pivoted to a xedobject and adapted to be received between the arms of the U-shapedplate, and means to limit the movement of said trip nger in onedirection.

In testimony whereof, we affix our signatures, in presence of twowitnesses.
